This library is used by a number of different libraries in the system. Make it easy for platform libraries to use this library and create an actual exported include file. Change the names of the functions to reflect the new name of the library. Run clang_format on the async_safe_log.cpp file since the formatting is all over the place. Bug: 31919199 Test: Compiled for angler/bullhead, and booted. Test: Ran bionic unit tests. Test: Ran the malloc debug tests. Change-Id: I8071bf690c17b0ea3bc8dc5749cdd5b6ad58478a
